ok, I bought a miller bobcat 225g with a onan p216g. I had always wondered why it puked out oil out of the fuel pump. needless to say i found out what was causing it. I found that I had 2 bent intake valves and lost the seat in on of them and as of right now the engine is FUBAR'D as of right now. So here is the million dollar question of the day... The welder is a 1991 model according to MILLER, so I am guessing the engine is a 1990-1992.. I found another p216g with very little run time, but before i do that i was wondering if these engines will swap out or if I am going to run in to problems with the crank mating to the generator...
